Title: Improvements in or relating to roof structures
Inventor: AUBANEL JOHN EDWARD
IPC: E04D13/16
Filed: 1967-10-30
Abstract: 1,195,739. Roofs. E. J. CLAY Ltd. 29 Jan., 1969 [30 Oct., 1967], No. 49211/67. Heading E1W. Insulation for a roof structure comprises two identical wedge shaped panels formed by dividing a panel of rectangular section conk board, the two wedge-shaped panels being assembled with their wide ends abutting each other and their sloping faces uppermost. The length of the panel, in this case, is equal to half the width of the roof, if, however the length of the panel is too short to provide the required span, the panel may be regarded as made up from a plurality of slabs cut from identical blocks.

Title: Improvements in or relating to nuclear reactors
Inventor: BENZLER HARTWIG
IPC: G21C3/36
Filed: 1968-10-18
Abstract: 1,222,718. Reactors. H. BENZLER. 18 Oct., 1968, No.49407/68. Heading G6C. A fast gas-cooled nuclear reactor comprises a plurality of flat plate-shaped fuel elements each including ceramic fuel and a metallic casing. The thickness of the fuel and the spacing between adjacent elements in each part of the reactor are so arranged that throughout the reactor at full load the inner parts of the fuel are at the same temperature, also the fuel casings are at the same temperature. The pressure loss can be reduced to at least one half in comparison with an equivalent reactor core having rod-shaped elements, which is particularly important for gas-cooled reactors. If the elements of the breeding cover, i.e. the cover of a jacket around the reactor core, are formed in a similar way to the core elements, then a reduction of the pressure loss by a factor of from 4 to 6 is achieved. Furthermore, the volume of the cooling medium in the outer radial zones can be reduced, resulting in the reactor accommodating more fuel and the thermal loading of the outer cooling channels being advantageously raised. Also, by achieving the maximum permissible fuel temperature in the whole reactor core, the negative temperature coefficient of the reactivity is advantageously increased. The fuel elements may be assembled in bundles with the aid of spacers and each bundle inserted in an outer casing or in a support member. In a particular .construction, several bundles of fuel elements are stacked one upon another in each outer easing with adjacent bundles angular staggered, e.g. by 90 degrees. In order to avoid the pressure build-up of fission product gases, the interior of each fuel element is maintained by suction through a communicating duct system at a pressure below that of the cooling medium. The ceramic fuel may be inserted and fixed in the metallic casings in the form of prepressed panels. The metallic casings may be interrupted as in a cage, by which means a free diffusion of the fission products is made possible which results in a reduction of the metallic components in the reactor core and a simultaneous increase in the breeding rate. In an example, the fuel is a UO 2 -PuO 2  mixture of 20 to 25% by wt. fission material (U-235 and Pu) enrichment within a casing of austenitic steel. The cooling medium is CO 2 . The reactor core is surrounded on all sides by a jacket formed from a plurality of casings each containing stacked bundles of plate-shaped breeding elements.

Abstract: 1,088,130. Waste disposal apparatus. T. C. R. SHEPHERD. March 31, 1966 [Nov. 23, 1965], No. 49610/65. Heading B2A. A waste disposal apparatus comprises a waste inlet 9, Fig. 1, to ducting 6 leading down to a comminutor (not shown) driven to comminute waste, and means to produce a generally transverse curtain of water above the comminutor, to prevent waste being thrown upwards beyond the curtain during operation. The curtain of water which impinges on the ducting 6 leading to the comminutor chamber 3 is produced by a nozzle 16 having an angled slot 19 and located in a wall of the ducting. Closing a lid 11 actuates a switch 15 to start the comminutor and the water flow, which may be via a pump. The water feed to the curtain nozzle may be interconnected with a flow to the comminutor impeller. In a second embodiment, particularly for the comminution of bed-pans, a dome-shaped lid 30, Fig. 2, carries a sealing flange 31 received in a lip 32 of a top panel 33, the lip being backed by a resilient annular seal 34 around the top edge of a duct 35. A nozzle 36 is carried centrally beneath the lid from a bored housing 37 supplied with water via a bored hinge and arm assembly, to provide a conical sheet water curtain 44. In a further modification, the nozzle may be carried by a rigid tube depending from the lid.

Title: Apparatus for determining the position of a remote object
IPC: F41G7/30
Filed: 1977-12-01
Abstract: In order to increase the measurement accuracy in the case of determining the offset of an object from a reference line which is defined by an optical measuring device, a rotatable shutter (12) is arranged in the imaging plane of the objective (11) of said measuring device. The shutter (12) has an opening (21) which is bounded on one side by a straight line and by a logarithmic spiral on the other side. The radiation pulses which strike a photosensor (15) during rotation of this shutter have a different length, depending on the distance of the image in the imaging plane from the centre, and have a different phase angle with respect to the shutter rotation, depending on the angular position of said image. The position coordinates of the imaged target object with respect to the reference line can be determined by means of evaluation electronics (17) in this manner, the measurement accuracy being linear with respect to the distance of the image from the centre of the shutter, that is to say being small close to the centre. <IMAGE>

Abstract: 1493106 Variable-speed gear G W BURTON 11 Feb 1975 [12 Nov 1973] 52337/73 Heading F2D A steplessly variable ratio drive, between a one, two or more speed motor 10 and the rotary pump head 12 of an infusion apparatus, comprises oppositely directed input and output cones 20, 22, connected by a drive-transfer wheel 26, which is pressed downwards by a spring into the space between the cones and after relaxing spring pressure can be traversed along their adjacent surfaces by a screwed spindle 20, to settings indicated by a scale 40, reading delivery rate, and adjustable in the direction of movement of the wheel 26 to permit calibration in terms of a measured delivery rate. The infusion apparatus comprises a triangular pump head 12 over which is tensioned a stationary silicone rubber tube 18, which is locally flattened by the apices of the head 12 as it rotates under the tube, the unflattened parts between the apices carrying incremental amounts of liquid along the tube. The speed ratio of the friction gear bears a hyperbolic relation to the traverse distance of the wheel 26, but, in view of linear deviations produced by parameters such as the size of the pump head, the characteristics and tension of the tubing, and the head of the source of liquid, the axial adjustment of the scale, to suit the calibrated rate, introduces deviation from the hyperbolic relation. The Specification compares the effect of these deviations on both hyperbolic and logarithmic scales, and concludes that for deviations below 15%, the former is acceptable, whilst above that the latter is preferable.
